"We are aware of the allegations and have been conducting a thorough review of the matter," Tittle said.

The allegations were first reported by Salt Lake City radio station 1280 the Zone. The NCAA will not confirm or deny any ongoing NCAA investigations.

Sam Leaf, a manager of former BYU wide receiver Cody Hoffman, told 1280 the Zone that Hoffman had been contacted by BYU "a couple of months ago." The school requested Hoffman to come in and answer questions about possible improper benefits provided to players.

Leaf told the radio station Hoffman refused to talk to the school and was focused on moving on to the NFL. Leaf said he was confident Hoffman had not received any illegal benefits, but Leaf wouldn't comment if he knew others that were involved.

Hoffman, who had a team-high 57 receptions as a senior last fall, was not selected in the NFL Draft. He signed a free agent contract with the Washington Redskins.

Ironically, BYU is the only school that has won an AP national championship in football and has never had a major NCAA violation or received NCAA sanctions.

"I would really like to be the alternative," Mendenhall said in 2011. "I'm not saying we're perfect or there couldn't be a violation at some point, I would really like a program to be successful and show that you can win by playing by the rules and doing it with high standards.

"It's becoming increasingly difficult with the booster population. I think that's what most programs are struggling with."
